[SCREEN INSPECTOR]

Frame Skip & Stutter Test

Detect if your monitor is dropping internal frames when running at high refresh rates (144Hz, 240Hz, 360Hz) or custom overclocks.

Camera Pursuit Photo Grid

Take a 1/10s camera photo of the moving row below.

Measured Hz: Checking...
📸 Healthy Monitor (Continuous Row):

In your photo, you should see a continuous, unbroken sequence of adjacent lit blocks (e.g. 1 2 3 4 5 6 7 8). Every frame was displayed by your panel.

⚠️ Frame Skipping Monitor (Black Gaps):

If your photo shows black missing gaps between lit blocks (e.g. 1 2 [GAP] 4 5 [GAP] 7), your monitor is failing internal frame delivery and dropping frames.

Frequently Asked Questions

What causes a monitor to skip frames?

Frame skipping occurs when a monitor fails to display every frame sent by the GPU. This commonly happens when overclocking a monitor beyond its panel limits, using low-bandwidth DisplayPort/HDMI cables, or using unverified display custom resolutions.

How do I test for frame skipping with a camera photo?

Start the pursuit grid test below, set your camera or smartphone camera to Manual/Pro mode with a 1/10 second (0.1s) shutter speed, and take a photo of the moving blocks. A healthy monitor shows a continuous row of lit blocks. A frame-skipping monitor shows black missing gaps between lit blocks.

How do I fix frame drops on my monitor?

To fix frame drops: 1) Revert custom monitor overclocks to native panel refresh rate (e.g., 144Hz), 2) Upgrade to a VESA-certified DisplayPort 1.4 or HDMI 2.1 cable, and 3) Update your graphics card drivers.

Is frame skipping the same as low FPS?

No. Low FPS means your GPU is generating fewer frames per second (e.g. 30 FPS game). Frame skipping means your GPU IS sending 144+ frames, but your monitor hardware drops frames internally, causing severe motion micro-stutter.
